My answer might be a little late in coming but I thought I'd let you know that the fix changed my problem as well!
Thanks! The autowire-worker sure is *very* useful because it reduces xml clutter, which in my book is a good thing. It would probably make sense to move it into a seperate project, like HLS did for the flash-property strategy for example. That way everyone who wants to use it can just download the drop-in jar. > --- Ursprüngliche Nachricht --- > Von: "James Carman" <[EMAIL PROTECTED]> > An: "'Tapestry users'" <users@tapestry.apache.org> > Betreff: RE: Tapernate-Example HiveMindAutowireWorker Problem > Datum: Tue, 9 May 2006 20:13:50 -0400 > > Oh, sorry.
